Preformed dryer vent cleaning and heating maintenance on a single system gas unit. Presented client with before and after pictures of 5e dryer vent cleaning. On the heating maintenance I checked all safeties to ensure everything was in good working order, all tested within manufacturer specifications. Temperature being supplied to the home was 106 degrees and 75 coming into the unit. Filter did not need to be changed at this time. Unit was back to cooling and cooling upon departure. Provided estimates for a level 2 duct cleaning.
